Summary: The configuration files for setting up a caching name server.

The caching-nameserver package includes the configuration files which
will make BIND, the DNS name server, act as a simple caching nameserver.
Many users on dialup connections use this package along with BIND for
such a purpose.
If you would like to set up a caching name server, you'll need to install
the caching-nameserver package; you'll also need to install bind.
